Why does my ex want to hurt me when he knows I'm already hurting?

Anonymous
Was with my ex for 4 years, have 2 kids together and have been split up for a year. He has recently starting seeing someone else and is rubbing it in my face

First of all he wanted us to be friends, telling me I was a lovely lady and should get it on with a new man, at times flirty with me and constantly texting and ringing if I didn't reply. I told him I couldn't be friends at the moment, he wasn't happy about it. Now he is telling me how much his new girlfriend is better than me,he trusts her (we split because he had trust issues), their so happy etc. Telling me I'm basically a crap person, crap mother etc..

Why be so nasty to me when he knows I'm hurting already?

He was quite controlling, didn't want me to see my friends, didn't trust me(the trust issues were from his previous a relationship). It all got to much for me so I split with him
